AbstractPotencial and polarization resistance of PC wires on existing post-tension type PC bridges
repaired by re-grouting method using LiNO2-containg solution were measured for 3 or 4 years in order toevaluate repair performance and durability of it. All potencial maintain nobler than -200(mV vs CSE)
that shows low probability of corrosion. All potencial and polarization resistance show almost samevalue during monitoring period. Therefore it is considered that repair performance of the method
maintain good condion on existing PC bridges.
